Title: Time Indexes and Time Indexed Series Description: Functions and S3 classes for time indexes and time indexed
series, which are compatible with FAME frequencies. Author: Jeff Hallman Maintainer: Jeff Hallman

Title: R interface to Tisean algorithms Description: Algorithms for time series analysis from nonlinear dynamical systems theory originally made available by Rainer Hegger, Holger Kantz and Thomas Schreiber at the site http://www.mpipks-dresden.mpg.de/~tisean/ . A related R package (tseriesChaos by Antonio, Fabio Di Narzo) contains rewritten versions of a few of the TISEAN algorithms. The intention of the present package is to use the TISEAN routines from within R with no need of manual importing/exporting. It is in a beta version state, though most of the functions should be usable. Correspondence should be sent to either Marji Lines, lines@dss.uniud.it, or to the current maintainer of the package. This package only contains R interface code. It requires that you have the Tisean-3.0.1 algorithms available on your computer. Author: TISEAN authors: Rainer Hegger, Holger Kantz, Thomas Schreiber.

Title: SAGA Geoprocessing and Terrain Analysis in R Description: RSAGA provides access to geocomputing and terrain analysis functions of SAGA from within R by running the command line version of SAGA. In addition, several R functions for handling and manipulating ASCII grids are provided, including a flexible framework for applying local functions (including predict methods of fitted models) or focal functions to multiple grids. SAGA GIS is available under GPL via http://sourceforge.net/projects/saga-gis/. Author: Alexander Brenning Maintainer: Alexander Brenning

Title: R interface to the PostgreSQL database system Description: Database interface and PostgreSQL driver for R
This package provides a Database Interface (DBI) compliant
driver for R to access PostgreSQL database systems.
In order to build and install this package from source, PostgreSQL
itself must be present your system to provide PostgreSQL functionality
via its libraries and header files. These files are provided as
postgresql-devel package under some Linux distributions.
On Microsoft Windows system the attached libpq library source will be used.
A wiki and issue tracking system for the package are available
at Google Code at https://code.google.com/p/rpostgresql/ . Author: Joe Conway, Dirk Eddelbuettel, Tomoaki Nishiyama, Sameer Kumar Prayaga (during 2008), Neil Tiffin Maintainer: Tomoaki Nishiyama

Title: Examples using Rcpp to interface R and C++ Description: Examples for Seamless R and C++ integration
The Rcpp package contains a C++ library that facilitates the integration of
R and C++ in various ways. This package provides some usage examples.
Note that the documentation in this package currently does not cover all the
features in the package. It is not even close.
It does however provide a few example based on both the (deprecated)
`classic' API and the current Rcpp API which supercedes it. As such, it
can help in porting from the older API to the newer API. Author: Dirk Eddelbuettel and Romain Francois, based on code written
during 2005 and 2006 by Dominick Samperi Maintainer: Dirk Eddelbuettel and Romain Francois

Title: A Parallel Analysis With Polychoric Correlation Matrices Description: The Function performs a parallel analysis using simulated
polychoric correlation matrices. The nth-percentile of the
eigenvalues distribution obtained from both the randomly
generated and the real data polychoric correlation matrices is
returned. A plot comparing the two types of eigenvalues (real
and simulated) will help determine the number of real
eigenvalues that outperform random data. The function is based
on the idea that if real data are non-normal and the polychoric
correlation matrix is needed to perform a Factor Analysis, then
the Parallel Analysis method used to choose a non-random number
of factors should also be based on randomly generated
polychoric correlation matrices and not on Pearson correlation
matrices. Version 1.1.1, fixed a minor bug in the regarding the
estimated time needed to complete the simulation. Also in this
version, the function is now able to manage supplied
data.matrix in which variables representing factors (i.e.,
variables with ordered categories) are present and may cause an
error when the Pearson correlation matrix is calculated.
Version 1.1.2 simply has updated the function that calculates
the polycoric correlation matrix due to changes in the psych()
package. Version 1.1.3 tackles two problems signalled by users:
1) the possibility to make available the results of simulation
for plotting them in other softwares. Now the
random.polychor.pa will show, upon request, all the data used
in the scree-plot. 2) The function polichoric() of the psych()
package does not handle data matrices that include 0 as
possible category and will cause the function to stop with
error. So a check for the detection of the 0 code within the
provided data.matrix is now added and will cause the
random.polychor.pa function to stop with a warning message. Author: Fabio Presaghi & Marta Desimoni Maintainer: Fabio Presaghi

Title: Tools for splitting, applying and combining data Description: plyr is a set of tools that solves a common
set of problems: you need to break a big problem down
into manageable pieces, operate on each pieces and then
put all the pieces back together. For example, you
might want to fit a model to each spatial location or
time point in your study, summarise data by panels or
collapse high-dimensional arrays to simpler summary
statistics. The development of plyr has been generously
supported by BD (Becton Dickinson). Author: Hadley Wickham Maintainer: Hadley Wickham

logic expression presented by a truth table or a logic tree. Has been particularly
developed for logic expressions resulting from a logic regression analysis, i.e.
logic expressions typically consisting of up to 16 literals, where the prime implicants
are typically composed of a maximum of 4 or 5 literals.License: LGPL (>= 2)Packaged: 2011-12-29 01:52:01 UTC; schwenderRepository: CRANDate/Publication: 2011-12-30 11:23:02

Title: A package for graphical modelling in R Description: The gRbase package provides certain general constructs which are used by other graphical modelling packages. This includes 1) the concept of gmData (graphical meta data), 2) several graph algorithms 3) facilities for table operations, 4) functions for testing for conditional independence. gRbase also illustrates how hierarchical log-linear models (hllm) may be implemented.

Title: Generalized ridge trace plots for ridge regression Description:
The genridge package introduces generalizations of the standard univariate
ridge trace plot used in ridge regression and related methods. These graphical methods
show both bias (actually, shrinkage) and precision, by plotting the covariance ellipsoids of the estimated
coefficients, rather than just the estimates themselves. 2D and 3D plotting methods are provided,
both in the space of the predictor variables and in the transformed space of the PCA/SVD of the
predictors. Author: Michael Friendly Maintainer: Michael Friendly

Title: Stochastic Frontier Analysis Description: Maximum Likelihood Estimation of
Stochastic Frontier Production and Cost Functions.
Two specifications are available:
the error components specification with time-varying efficiencies
(Battese and Coelli, 1992)
and a model specification in which the firm effects are directly
influenced by a number of variables (Battese and Coelli, 1995). Author: Tim Coelli, Arne Henningsen Maintainer: Arne Henningsen
